Matlab-零填充（2）

Question

任何人都可以提供帮助？不知道为什么会出错？ ???

Assignment has more non-singleton rhs dimensions than non-singleton
subscripts Error in ==> create_padded_image at 17
padded_image(padding+1:padding+image_size(1),
padding+1:padding+image_size(2)) = image; Error in ==>
create_padded_image at 9 padded_image = create_padded_image(image)

function padded_image = create_padded_image(image, padding)  
if nargin < 2         
    % if no padding passed - define it.         
    padding = 5; 
end
if nargin < 1     
    % let's create an image if none is given
    image = imread('GreyScale.bmp');
    padded_image = create_padded_image(image) 

end  
    % what are the image dimensions? 
    image_size = size(image);   
    % allocate zero array of new padded image 
    padded_image = zeros(2*padding + image_size(1), 2*padding + image_size(2));
    % write image into the center of padded image 
    padded_image(padding+1:padding+image_size(1), padding+1:padding+image_size(2)) = image; 
end

尝试

image_size = size(image);
padded_image = zeros(2*padding + image_size(1), 2*padding + image_size(2), size(image,3), class(image));
padded_image(padding+1:padding+image_size(1), padding+1:padding+image_size(2), :) = image;
